Every output I do using the Mac version of the Topaz Video Desktop app exports with random glitching. Have tried the default 4k and FHD output all with that same problems.
Thank you for sharing the screenshots, this looks like a possible overheating situation, but the second frame with the ghosting is a bit odd.
Can you send the logs from the app, and a sample fo teh original file along with the exported clips to the support team so we can look deeper into this and try to replicate it?
You can send the logs to this email address: help@topazlabs.com and if the files are too large to attach to the email, you can use the Dropbox link below. Just include the file names in the email so we can get them for testing.
To gather logs, please select Help > Logging > Get Logs for Support and attach the zip file to your reply.
Here is a video to help with the steps of how to collect the logs.
Thank you for responding, Kyle. I have emailed the log files, and the videos are currently uploading. The App is running on an Apple M3 Max MacBook Pro with 48GB of RAM.
